Description

  The present invention relates to a self-luminous line-of-sight guidance sign that is installed mainly on the shoulder of a road or in a median strip and guides the line of sight of a driver of a vehicle.

  Conventionally, a self-luminous gaze guidance mark provided with a light emitting unit using a self-luminous body is often used as a gaze guidance sign installed near a road.

  In recent years, LEDs (light-emitting diodes) that have a high directivity of light and a long emission lifetime have been widely used as self-luminous bodies. Further, the line-of-sight guidance mark is provided with a solar cell module and a storage battery, and the power generated by the solar battery is stored in the storage battery and used as a power source for causing the self-luminous body to emit light. It has become like this.

  As this type of self-luminous gaze guidance mark, for example, a solar cell module is provided on the upper end surface of the housing, and in the housing, in addition to a light-emitting unit that includes a plurality of self-luminous materials, Some have a control circuit board or a storage battery for controlling (Patent Documents 1 and 2).

  According to the line-of-sight guide described in the above-mentioned patent document, a control circuit board and a storage battery are arranged behind a board or the like to which a plurality of self-luminous bodies (LEDs) are attached, and are provided on the upper end surface of the casing. The electric power generated in is stored in the storage battery and further supplied to the control circuit and the LED.

According to such a gaze guidance mark, it is possible to perform a suitable gaze guidance regardless of day or night without requiring an external power source.

  However, in such a line-of-sight guidance mark, since storage and discharge are always repeated, deterioration of performance of the storage battery over time is unavoidable, and it is necessary to periodically replace the storage battery.

  However, when replacing the storage battery in the line-of-sight guide described in the above-mentioned patent document, after removing the front cover and taking out the light emitting part, it is necessary to replace the storage battery arranged in the back. Therefore, the operator often mistakenly damages the substrate, the control circuit, the wiring connecting them, and the like to which the light emitting unit is attached.

  In this regard, there is an apparatus in which an opening is formed on the back surface of the housing, and a control circuit and a storage battery are stored on the back surface inside the housing so that the opening is covered with a back plate. With such a structure, when replacing the storage battery, it is not necessary to remove the light emitting part on the front side, and it becomes possible to remove the back plate on the back side and take out only the storage battery for replacement. Therefore, the replacement work itself of the storage battery is simplified.

  However, even in such a structure, when the storage battery is taken out, the back side of the light emitting unit, that is, the back side of the board to which the LED is attached or the control circuit board is exposed, so when removing the storage battery, or When installing a new storage battery, an operator may accidentally damage a substrate, a control circuit, or the like.

  Moreover, in any of the above-described conventional visual guidance indicators, the inside of the housing is hollow. This housing is formed of a metal such as an aluminum alloy or a resin material, but is weak in strength because the inside is hollow. In addition, distortion, twisting, etc. are likely to occur due to long-term outdoor installation, which creates a gap in the joint surface between the housing and the solar cell module, and rainwater enters the housing. End up.

  In this regard, it is conceivable to form ribs in the housing in order to improve the strength of the housing. However, in metal housings, forming ribs by welding or the like is a very troublesome operation. is there. When the casing is molded from a resin material, only a specific direction in terms of molding technology, that is, a rib extending inward from the inner peripheral wall of the casing can be formed in consideration of the mold opening direction. In addition, it is possible to consider the method of forming the casing members to be thick, and the correspondence of forming a large number of ribs, but there are also disadvantages of increased product cost and problems with other storage members and wiring. Will occur.

  The present invention has been made in order to overcome the above-described problems, and allows the storage battery to be easily replaced without damaging other members such as a substrate to which a self-luminous body is attached. The purpose is to provide a gaze guidance mark.

  Another object of the present invention is to provide a line-of-sight guide that can reliably and stably hold a storage battery for a long period of time regardless of the vibration of the road. To do.

In order to solve the above problems, the self-luminous gaze guidance mark according to the present invention is a self-luminous gaze guidance mark including a light emitting unit and a storage battery in a housing,
The housing is opened forward and rear to form a light emitting unit storage chamber and a storage battery storage chamber, respectively.
A partition wall that is substantially orthogonal to the opening direction and divides the light emitting unit storage chamber and the storage battery storage chamber is formed integrally with the housing ,
A plurality of ribs rising from both the inner peripheral wall of the casing and the partition wall surface are formed on the inner peripheral wall and the partition wall surface of the storage battery storage chamber side, and the storage battery is press-fitted between the end portions of the plurality of ribs and sandwiched between the ribs. It is characterized by holding .

  According to the case of the self-luminous line-of-sight guidance mark according to the present invention, the board on which the self-luminous body is attached, the control circuit board, and the like are housed on the front side (light emitting unit housing chamber) of the housing, and the rear side (storage battery housing chamber) ) And a partition wall is formed between the light emitting unit storage chamber and the storage battery storage chamber.

  Thus, when replacing the storage battery, only the storage battery can be taken out and replaced from the back side of the line-of-sight guidance mark. At this time, since the partition wall is present, the back side of the light emitting unit is not exposed. In other words, this partition wall also serves as a protective wall that protects the back side of the light emitting part, and the operator can easily store the storage battery without damaging the back surface of the substrate on which the light emitting body is attached or the control circuit board. Can be exchanged. In addition, the strength of the housing is dramatically improved by the partition walls.

A plurality of ribs rising from both the inner peripheral wall of the housing and the partition wall surface are formed on the inner peripheral wall and the partition wall surface of the storage battery storage chamber, and the storage battery is sandwiched and held between the end portions of the plurality of ribs. It is made to do .

  In this way, the partition wall is formed, and the plurality of ribs rising from both the inner peripheral wall of the casing and the partition wall surface are formed, so that the strength of the casing is further improved. In this regard, when the casing is formed of a resin material, ribs extending in the front-rear direction can be integrally formed in the casing with the partition wall as a base, so that the strength of the casing can be further improved. .

  Furthermore, since the plurality of ribs are formed and the storage battery is held between the tip portions of the plurality of ribs, the structure is strong against vibration. That is, since this type of gaze guidance mark is installed in the vicinity of a road, it is greatly affected by vibration caused by the passage of a vehicle or the like. A member that normally occupies a large proportion of the total weight of the line-of-sight guidance mark is a storage battery. Therefore, if the storage battery is not firmly fixed, the storage battery may rattle inside the visual guidance indicator and not only affect the circuit inside the visual guidance indicator, but also damage the visual guidance indicator itself.

  In this regard, according to the line-of-sight guidance mark according to the present invention, the storage battery is firmly held by the plurality of ribs formed in the housing, so that the storage battery is surely and stable in spite of the vibration on the road as described above. Retained.

  In order to further reduce the influence of vibration, it is more preferable that the storage battery is held at a position where the gravity center position of the line-of-sight guidance mark and the gravity center position of the storage battery housed in the casing substantially coincide.

  In the line-of-sight guidance mark according to the present invention, it is preferable that an opening window is formed in the partition wall. In this way, it is possible to suitably wire and arrange the connection means for connecting the self-luminous body, the control circuit, etc. stored in the light emitting unit storage chamber and the storage battery stored in the storage battery storage chamber. Become. In addition, the presence of the opening window facilitates removal from the mold in forming the housing.

  Furthermore, in the line-of-sight guidance mark according to the present invention, it is preferable that the storage battery is held and fixed in close contact with the partition wall so as to cover the opening window.

  If it does in this way, since a light emission part storage chamber and a storage battery storage chamber can be interrupted | blocked, the water stop effect will increase. Therefore, even if rainwater or the like enters the storage battery storage chamber, the rainwater does not enter the light emitting unit storage chamber, so that damage to the line-of-sight guide mark due to intrusion of rainwater can be minimized.

  As described above, according to the self-luminous line-of-sight guidance mark according to the present invention, the partition wall is formed between the light-emitting unit storage chamber and the storage battery storage chamber. The storage battery can be easily replaced without damaging the attached board or the back of the control board. Moreover, the strength of the casing is dramatically improved.

  In addition, if a plurality of ribs rising from both the inner peripheral wall of the casing and the partition wall surface are formed, the strength of the casing is very excellent due to the action of the partition walls and ribs.

  Furthermore, since the storage battery is sandwiched and held by the plurality of ribs, and the storage battery can be stably held in the housing, the structure is extremely strong against road vibration.

  Further, if an opening window is formed in the partition wall, a connecting means for connecting the self-luminous body, the control circuit, and the like stored in the light emitting unit storage chamber and the storage battery stored in the storage battery storage chamber is preferable. Wiring and placement are possible.

  Furthermore, if the storage battery is held and fixed in close contact with the partition wall so as to cover the opening window, the water-stopping effect is enhanced, so that damage to the gaze guidance mark due to intrusion of rainwater or the like is minimized. Can do.

  In addition, LED is used for a self-light-emitting body. As the self-luminous body, in addition to LEDs, halogen lamps, metal halide lamps, cathode tubes, electroluminescence, xenon lamps and the like are used as appropriate. In general, LEDs having high luminance and long life are preferably used. .

  FIG. 3 is a perspective view showing an embodiment of a self-luminous line-of-sight guide according to the present invention. 4 is a perspective view of the housing of FIG. 3 as viewed from the back side. 5 is a front view of the housing of FIG. 3, FIG. 6 is a rear view thereof, and FIG. 7 is a side sectional view taken along line BB of FIG.

  As shown in FIGS. 3 and 7, the front side in the housing 2 is provided with a front opening that opens forward so as to store the light emitting unit 3, and this front opening forms a light emitting unit storage chamber 22. doing. As shown in FIGS. 4 and 7, the housing 2 is provided with a back opening that opens toward the back (rear) on the back side, and this opening forms a storage battery storage chamber 23.

  The housing 2 is obtained by molding a synthetic resin such as polyethylene, ABS resin, FRP, polycarbonate, AAS or the like. In this embodiment, the housing 2 is manufactured by injection molding. The mold is opened in the front-rear direction of the housing, and the molded product (housing 2) is removed from the mold. It is produced.

  As shown in FIGS. 3 to 7, the housing 2 has a partition wall 24 formed at a substantially middle portion in the front-rear direction of the housing. Further, as shown in FIG. 4, a plurality of ribs 25 are formed in the storage battery storage chamber 23. At this time, since the partition wall 24 is formed in the housing 2, not only from the inner peripheral wall of the housing 2, but also a rib that rises from the partition wall 24 in the forward direction of the housing 2 can be formed. Thus, the rib 25 extending in a plurality of directions can be formed. In the line-of-sight guide 1 of the present invention, the plurality of ribs 25 are configured to rise from both the inner peripheral wall surface of the housing 2 and the partition wall 24. Due to the partition walls 24 and the ribs 25, the strength of the housing 2 is significantly improved.

  Further, as shown in FIGS. 3 to 7, a plurality of opening windows 241 are formed in the partition wall 24, and the light emitting unit storage chamber 22 and the storage battery storage chamber 23 are connected to the opening windows 241. Thereby, the connecting means for connecting the self-luminous body 33, the control circuit board 35 and the like stored in the light emitting unit storage chamber 22 to the storage battery 5 stored in the storage battery storage chamber 23 is suitably wired and arranged. To be able to.

  As shown in FIG. 8, the storage battery 5 is stored in the storage battery storage chamber 23 of the housing 2, and this storage battery 5 is between the tip portions (251 to 258) of the plurality of ribs 25 formed in the storage battery storage chamber 23. And is stored so as to be held. In other words, this rib has dimensions such that the length dimension between the end portions (251 and 252, 253 and 254, 255 and 256, 257 and 258) of the opposing rib 25 is the same as or slightly smaller than the vertical and horizontal dimensions of the storage battery 5. The storage battery 5 can be held between the tip portions. Thereby, the storage battery 5 can be press-fitted between the tip portions (251 to 258) of the plurality of ribs 25, and the storage battery 5 can be reliably and stably held in the housing 2.

  Furthermore, as shown in FIG. 3 and FIG. 8, the tip portions (251 to 258) of the rib 25 for sandwiching the storage battery 5 have a mountain shape. Since the housing 2 is formed of a resin material as described above, it is easy to press-fit the storage battery 5 between the ends (251 to 258) of the rib 25, and it is elastic and stable. Thus, the storage battery 5 can be sandwiched.

The rib 25 has a tapered shape in which the height dimension of the rib is slightly reduced from the rising end on the partition wall 24 side toward the back surface of the housing 2, that is, the tip of the rib 25. If the distance between (251 to 258) becomes longer toward the back side of the casing 2, the press-fitting of the storage battery 5 becomes easier. Moreover, by doing in this way, there exists an advantage that the demolding of the molded product from a metal mold | die becomes easy in the molding process of the housing | casing 2. FIG .

  In this embodiment, after storing the storage battery 5 in the housing 2 and the storage battery storage chamber 23 as described above, the storage battery 5 is covered with the back plate 6, and the back plate 6 is fixed to the housing 2 by screwing ( (See FIG. 9).
